Title: Structure for mounting dampers on vehicles
Inventor: CHINO KENJI
IPC: B60G9/02
Filed: 1998-06-30
Abstract: A structure for mounting a hydraulic damper to a vehicle body is provided.  The damper has a first end and a second end.  The vehicle includes a vehicle frame that has a first bracket connected to the first end and an axle that has a second bracket connected to the second end.  The axle is arranged to be pivotal with respect to the frame.  The damper changes its length based on a swinging action of the axle.  The first bracket has a first support hole.  The second bracket has a second support hole.  The first end has a first through hole and the second end has a second through hole.  The first end and the second end of the damper are rotatably connected with the first bracket and the second bracket, respectively, by a shaft extending through at least one of the support holes and the associated through hole in a rotatable manner about its axis.  The shaft has an adjusting element for adjusting the length of the damper to an optimum value based on the rotation of the shaft, and rotation of the shaft is prohibited by a prohibiting mechanism to maintain the length of the damper in the optimum value.

Title: Downhole gravity tool
Inventor: WIGNALL ALBERT H
IPC: G01V7/02
Filed: 1998-09-21
Abstract: A tool for conducting gravimetry survey downhole in an earth formation includes a pressure vessel which houses a gravity sensor that is supported by a gimbal.  The gravity sensor is aligned with vertical before taking gravity measurements by a first stepper motor and a second stepper motor.  The first stepper motor incrementally rotates the gimbal about the pivot axis of the gimbal while the second stepper motor incrementally rotates the gimbal about the longitudinal axis of the pressure vessel.  The stepper motors are controlled by an electronic processor that responds to signals from an accelerometer assembly that measures the inclination of the pressure vessel with respect to vertical.  An elevator mechanism translates the gravity sensor from one station to the next inside the pressure vessel to make gravity measurements and an optical encoder monitors the position of the gravity sensor inside the pressure vessel.

Patent CA-2254104-A1 (CA)
Title: Method and apparatus for per traffic flow buffer management
Inventor: KLAUSMEIER DANIEL E
IPC: H04L12/56
Filed: 1997-05-09
Abstract: A method of managing oversubscription of a common buffer resource shared by a number of traffic flows in a cell switching network in response to the utilization of the common buffer resource. A buffer utilization threshold is established for each of the traffic flows. As new cells arrive, the global usage of the buffer resource is monitored. As the buffer utilization increases, the thresholds for each of the traffic flows are dynamically adjusted based upon the global usage of the buffer. Aggressive buffer allocations are scaled back when necessary, thereby leaving space for traffic flows which are relatively empty. In one embodiment, the thresholds are coded in mantissa and exponent form so that the scaling is accomplished by adjusting the exponent value.

Abstract: Since the introduction of bullnose corner bead (rounded outside corners), the laying of baseboard trim has become almost impossible.      The need for a 90° radius component (corner clip) has come to pass. The requirement of my present invention eliminates this laborious task. It allows the baseboard to sit on top of the anchoring tab, while butting up against the side of the component (corner clip). This component is very easy to install. You simply put it up to the corner and nail it in place. Caulking is required to hide any irregularities at the top and on the sides. This invention is made from a mould which required precise and exact measurements. This mould is used in a process called plastic injection moulding. The component can be made from nylon or plastic providing both strength and paintability.  The outermost face is finished by a process called electrical discharge machining (EDM). This allows latex paint to adhere to the component. As this component is higher at the top and proud on the sides, it has a universal look and fits all baseboards.

Inventor: MURAMOTO TAMAKI
IPC: A61P25/28
Filed: 1997-04-15
Abstract: The invention includes deleting codon segments from DNA expressing a native protein in order to obtain a shorter, soluble protein which mimics characteristics of an insoluble native protein. Soluble proteins of the invention are characterized by: (1) having less amino acids than the full length native protein; (2) having a higher degree of solubility than the native protein; (3) retaining the basic biological characteristics of the native protein such as (a) not being subject to enzymatic digestion and (b) causing disease. Soluble proteins of the invention are obtained by providing a DNA sequence which encodes a native protein and systematically removing codons, making copies of the shortened versions of DNA which are then expressed to provide the shortened proteins. The shortened proteins are then tested for solubility. Soluble proteins are then further tested to confirm that they retain the biological characteristics of the native protein.

Title: Method and apparatus for controlling condensation of gaseous hydrocarbon stream
Inventor: DEVERS BARNARD JAMES
IPC: F25J3/08
Filed: 1997-10-14
Abstract: In a cryogenic condensation scheme used for benzene removal in a process for liquefying natural gas, two series connected separation columns (10, 12) are provided with a feedstream (44) precooled in a heat exchanger (16) to a temperature that will at least condense the benzene component. In the first column (50), benzene is absorbed and vapor/liquid is separated with the liquid passed to the second column (60). The second column (60) provides an overhead vapor stream (68) conserved for processing to LNG, and a bottom stream comprising NGL. The cooling for condensation of gaseous feed in the heat exchanger is controlled by automatically manipulating bypass flow (38) around the heat exchanger responsive to measured vapor flow (80) from the second separation column. Accordingly, the amount of liquid (36) condensed is responsive to the flow rate of vapor withdrawn overhead from the second separation column.

IPC: G06F3/0354
Filed: 1999-05-28
Abstract: The functionality of a touchpad and fingerprint sensor into a single sensor.  This is achieved by using a conventional high resolution finger detecting sensor, such as a capacitive sensor, coupled to a processor running appropriate software which performs either fingerprint operations or finger motion detection as a function of the application required to be performed at any particular time by a user. More specifically, in a first mode for performing fingerprint operations, the software interacts with the capacitive sensor to obtain a fingerprint "image", if there is a finger in contact with the sensor, and to process the fingerprint images, such as analyzing it to detect patterns, storing the fingerprint image, or comparing the fingerprint image against other stored fingerprint images, a second mode, for performing finger motion detection, the software obtains successive fingerprint images and analyzes them to detect direction of motion and amount of motion, e.g., by identifying particular features of the fingerprint and determining their location in each of the successive fingerprint images. Advantageously, a savings in both cost and space required is achieved with respect to the prior art systems.

Abstract: L'invention concerne un procédé et un dispositif de connexion électrique et mécanique d'un composant électrique à grande puissance (111) qui transmet des signaux électriques haute fréquence aux conducteurs (120) d'une carte à circuits imprimés (119). Selon l'invention, ce composant comprend des connexions (114) qui sont en saillie sur la carte et soudées aux conducteurs (120) avec un matériau d'apport (112) sensiblement non sujet à une croissance du grain. Le composant subit des variations de température répétées. La liaison reliant les connexions (114) aux conducteurs (120) est donc soumise à des contraintes. La longueur des connexions est choisie en fonction d'une valeur de seuil prédéterminée relative à l'atténuation maximale admissible que peut subir le signal électrique haute fréquence lorsqu'il traverse le composant électrique à grande puissance par les connexions. Les connexions peuvent être conçues de manière à présenter une partie pliée dont l'angle d'inclinaison est déterminé en fonction de ladite valeur de seuil.
